Wiard/Malekko Borg 2 Filter

The Borg II is a vactrol-based multimode filter. The follow-up to the original Wiard "Borg Filters" module from the Wiard 300 series, the Borg II features a single filter, (the original 300-series module contained two), and is available in the Wiard 1200 Series format--(frac-rack)--direct from Wiard, as well as in the eurorack format, manufactured by Malekko Heavy Industry under license from Wiard.

The Borg II is prized for its fast, aggressive filtering, as well as it's ability to be used as a Low Pass Gate and create distinctive 'plucky' sounds.
